Xen used to teach linux
Hi,

Have anybody already have a xen system to teach linux (system and network administration).

I need some tips about create a xen system for let´s say 16 students

Students will connect via sshd with a xen domain (server - debian or fedora) and all students will have any kind of workstation (hardware/software).

How to size the server to host these domains? Maybe 128MB ram for domain plus 6GB for disk, and about the processor? The process in CPU will be minimum because all domains will have 1 and maximum of 2 clients.

Students will learning basic to advanced configurations of

Mail (sendmail/postfix)
Web (apache/php)
Samba
Databases (mysql/postgresql)
Networking (named, dhcpd, nfs, ftp, etc)
X

Any tip? Some experience about this? I think it will be like a server for hosting services. But the difference is that will serve only 1 or 2 connections at same time.
